ELEPHONE-Guard).

T 0 all whom it may concern Be it known that I, EDGAR O. LOEBER, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements {in Telephone Guards, of which the following is a specification.

My invention relates to a telephone guard, and the object of the invention is to provide a guard for a telephone transmitter which covers the mouthot-the transmitter and protects the same from the accumulation of dust a's'well asto prevent t efperson who uses the tei'ep'hone from breathing into the transmitter and'thereby depositipg' disease germs, all substantially as shown and described and particularly pointed out in' the claim.

In the accompanying drawings, Figure 1 is a perspective view of a telephone transmitter with my new and improved ard in using position thereon, and Fig. 2 1s a sectional elevation of the mouth piece or trumpet of the transmitter with'the guard in sectional elevation. Fig. 3 is a plan View of a modification of the guard itself.

The transmitter as thus shown is indicated by a and-the trumpet shaped mouth- ,piece'thereof by 2, which is of the conven- ,tional flaring type generally in use. The

'30 said guard 9 consists of a paper disk of a fairly substantial kind of paper, preferably. so that it will not be too easily torn, and which is provided with two segmental cuts or slits 3 and 4 above and below, respectively. though they might be placed at the sides if preferred and serve the same purpose. The said slits are not concentric one with the other but eccentric as plainly seen in Fig. 3, and so th'at'the guard may be drawn first over the top portion of the mouthpiece at the slit 3 and then over the other at the slit 4:- The border both above and below is then thrown baclrinto locking position as seen in Figs. 1 and 2 and the guard is in place. This construction also provides a central disk portion 5 which is practically separate from the border 6 except at the two side portions indicated by 7 where the two circular slits 3 and 4 termihate. The said central disk 5 and the border are thus held in unity and a tie is produced across the mouthpiece which holds the central disk firmly" upon the edge thereof Specification of Letters Patent.

all around and forms a diaphragm against which the sound of the voice is uttered the same as it would be into the transmitter if this guard were not present. From practical experience where this guard is used it is found that, if anything, the "transmission 1S clearer and more eii'ective through it than without it, even without perforations, but if desired the form shown in Fig. 3 maybe used and wherein a few perforations are shown. These, however, are relatively small, mere pin holes, and not such as to transmit either breath or dust to the interior. I use paper preferably, because it is cheap. and serves my purpose but any other 1113. tellll that will serve the purpose may be use Theborder 6 is purposely made of such width and shape as to provide a space for advertising and which is so plainly displayed or exposed that it can scarcely escape observation by a user of the telephone. The peculiar shape and arrangement of the slots 3 and 4 also is original andespecially advantageous in this that they serve "not only to fix the. guard firmly upon-the telephone where it cannot be blown oh by wind or knocked ofl in the every day use of the telephone, and the circular or crescent shape is material for thereason that only by'tln's shape can it be placed on the mouth piece,

It will be noticed that the actual space between said slots is considerably less than? the space across the mouth'of said piece and that they can be engaged thereon only by afixing one slot and then the other afterthe first one is drawn well baclt" over thenarrower portion of said mouth piece as in Fig. 2. Then the other is applied and pressed back also and the face of the guard' caused to close the mouth piece uniformly as to effectually hold the and tightly all around and said slotted portions se'r-ve to draw it tight to place as well tightening relation.

What I claim is: A guard for the 'mouth of a telephone guard in such transmitter consisting of a light flexible'mm} g terial, such as paper, and having a middle portion adapted to cover the said mouth andprovided with two oppositely disposed segmental slits eccentric to each other and terminating in the sides of the guard, the

- lock the same thereon and spread the middle In testimony whereof I affix my signature in presence of two witnesses.

space between the middle of said slits being less thanathe space between the ends of each slit across said middle portion, whereby the said guard can be hooked over the edge of the transmitter through said slits and both Witnesses:
